[Biojava-l] String for Symbol

[Emig, Robin]

	I would like to add a method for BasisSymbol

String getTokensString()
or 
String getTokens()

which would return a string consisting of all the tokens for that symbol.
This would be useful for actual crossproduct symbols such as  [act]. Right
now the get token returns a unique but uncomprehendable char for getToken,
and in order to get the string of tokens you have to iterate through a list
from getSymbols(). It was suggested that and additional method of String
getToken() be implemented, but I thought it would be better if the two
methods where less ambiguous.

Any comments....
