# Usage: cgprice [coin] [currency]
# 
#        [coin] may be specified as an id, symbol or name but must resolve 
#               to a valid id as found in the API /coins/list
#               If not specified, or empty, or invalid it defaults to BLOCK.
#        [currency] must be a member of API /simple/supprted_vs_currencies
