                                 Modified one import bitwise operator to a comparison operator (& to &&).
 4.0.35.ZC 04/29/2016            Modified version number as github contained 4.0.35 and wanted to be sure that users that downloaded
                                         that version would receive notification of the updated file.  This is the version

+4.0.35.ZC.2 10/03/2016          Correctedissues related to version 4.0.35.ZC and incorporated comments received by
+                                        users of the program as identified in the ZC forum including:
+                                        Modified the usage and installation instructions to try to provide 
+                                          clearer direction in particular areas.
+                                        Cleaned up some documentation.
+                                        Improved system response/notification following upload of a csv file.
+                                        Resequenced some coding for readibility and consistency.
+                                        Corrected sanitization code that was incorrectly implemented, in some cases 
+                                          requiring more information to be entered in an import file than expected or
+                                          planned.
+                                        Increased the usability of alternate primary keys in import/export of data.
+                                        Pulled some import file types into their own unique file to:
+                                          1) simplify readibility
+                                          2) reduce program load demand (at this time research indicates that files
+                                             incorporated within if statements are not loaded as part of the 
+                                             overall program execution until needed.)
+                                          3) Lead into other structures that could be added to the code to offer
+                                             further expandibility.
+                                          4) Maintain structures to also lead into code execution from outside of the
+                                             main program controller and offer an interface with external code.
+                                        Removed excess code execution that performed no function. In some cases by
+                                          commenting out the code, in others by removing it.
+                                        Modifying some functions to in some cases incorporate ZC code improvments
+                                          such as using zen_db_input instead of just addslashes as the ZC version
+                                          of the data cleansing is improved with later versions of ZC to use 
+                                          functions other than just the basic addslashes PHP code.
+                                        Furthered addressing PHP 7.X related warnings by further pre-defining variables
+                                          before their first use.
+                                        In some cases reduced the run time of some code by accessing PHP functions
+                                          to capture the expected/necessary data rather than unnecessary loops.
+                                        Improved error reporting screen now that the primary key can be changed.
+                                        Forced unsetting of variables in functions that generated "one-time use" 
+                                          variables.
+                                        Modified the install code to improve the process for future upgrades.
+                                        Updated one of the dropdowns to reflect the datatype included with that option.
+                                        Added German installation instructions.
+4.0.36.ZC                       Updated the curver to reflect the latest version that might be identified by other
+                                        users that perhaps previously downloaded 4.0.36.a from github.
