1st patch for fixing issue #93 (types mixing between CRML.mo and CRMLtoModelica.mo libraries)

[audrey-jardin]

Addition in CRML.mo of:

• type CRMLPeriod
• type CRMLClock
• block CRMLPeriodTimePeriod to convert a TimeLocator to a CRMLPeriod

And update of reference models and results for some unit tests of CRML_test.

This fixes the simulation of some verification models automatically generated by the compiler related to issue #93. See screenshot of test_report.html below.

It however remains some issues on the mapping between Clock and CRMLClock. Maybe good to discuss that with you @lenaRB.
