Added functions that provide information for block and glyph coverage

Added functions that provide information for block and glyph coverage.

Notes:
- The current method for loading in block names and ranges is temporary, FIXME message has been attached.
- Current method of calculating blocks iterates by block and creates a UnicodeSet per block, which is extremely inefficient. A better algorithm would be to iterate by the valid code points in the font. However, ICU does not provide a function that provides the full English name of each block, and I will need to think of a way to create such a mapping that deals with exceptions gracefully.
