Validate DotMP input parameters

[computablee]

Which issue are you addressing?

Closes #51

How have you addressed the issue?

A new method has been added to validate parameters. It is called

1. Within the internal For handler to ensure that all worksharing-for loops have valid parameters.
2. Within a ParallelRegion to ensure all parallel regions have valid parameters.
3. Within a Taskloop to ensure all taskloops have valid parameters.

How have you tested your patch?

Two new tests have been added:

1. Absent_params_shouldnt_except, which uses all default parameters with affected methods to ensure that the checks do not affect a lack of parameters.
2. Invalid_params_should_except, which has 100% coverage of the ValidateParams method to ensure that all paths are valid.
