Sesame Examples:

Usage: python SesameEx.py exampleName parameters ...
For example: 
	python SesamEx.py resolve "m8"

exampleName can be:

resolve name1 name2 name3 ...
	name1, name2 are names of targets to be resolved.
	For example: resolve m8 m32 m89
	Outputs a CSV formatted list as
		name,RA,DEC in deg

resolveList listName
	listName is name of a file containing names of targets
	Outputs RA and DEC appended to the end of each line 

aliases name1 name2 name3 ...
	Outputs aliases for given names

aliasesSOAP name1, name2, name3 ...
	Outputs aliases for given names

runAll
	Runs all examples
