initial setup
Initializing the repository, no configs or tests
Added plugins and verbose option
Changed name of the standard from P1788 to 1788
Added template files for plugins
Moved requirements.txt to root folder
Renamed ITL file extension to .itl
Added an ITL file

Note that this file contains assert statements that require an accurate output
for some functions even though a tightest implementation would satisfy the
standard. These tests may thus fail even though the implementation is
standard-compliant!
Renamed interval lib for C++
Merge remote-tracking branch 'origin/develop'

Conflicts:
	README
Adapted shebang in defaultGenerator
Fixed issue with relative paths
Deleted unnecessary divpair lines in C++ config
Changed delimiter for multiple outputs

Up to now, functions with multiple outputs switched to the next output with
a line '---NO'. This was changed to '*** next output' because YAML uses the
three dashes and to increase legibility.
Added examples to comments in template files
Renamed divToPair operation
Fixed data types for special intervals
Default generator now supports spaces in path

Previously, if the path name of the the cloned repository contained any spaces
or other strange characters, the script may not have worked if called
from another location.
Renamed operation

Several node classes have a method, previously called 'setDataType', now called
'setType'
Added long double tokens to template files
