Branch Intent: Create functions to make a set of tables whose data can be referenced by
	EnergyPlus table name, and whose data can be accessed by column & header name
Commit Intent: Rewrite report_tables function to call lines_table function, ensuring
	that when it is called, the 'tofloat' parameter of lines_tables will always be
	set to the default value of 'True'

 inside report_tables function...

*test_readhtml.py
-Removed function call to lines_table funcion since it this functionality is added to
 the report_tables function...
