added functionalities:
- created create_LowMACAAnnotation.R file that can retrieve all information from the internet and generate myPfam.RData myUni.RData and myAlias.RData
- myPfam.RData and myUni.RData are now shrunk in terms of columns
- myAlias.RData now comprises all HGNC genes (also the ones not included in myUni.RData like RNA genes and pseudogenes)
- myAlias.RData has 3 new columns:
	- Locus_Group
	- Locus_Type
	- MappedByLowMACA

bug fixes:
- removed lines from myPfam where Pfam_Fasta
- myPfam contains only genes in myUni
- Package name was changed from LowMACAdb to LowMACAAnnotation
