This script takes a dumpfile and produces a html based dump, which is a 
bit more easily analyzed. 

Arguments:
	-h 				This help
	-i <file>		Specifies the dump-file (input). If omitted, 'dumpdata.bin' is used	
	-o <filename>	Speciies the output file. If omitted, <curtime>.html is used.

In the future, we may implement so that scripts are invoked directly 
into a 'main' function, instead of being executed blindly. For future
compatibility, I have done so, but I invoke my main from here.
