Webservices can only handle single repeating units

[ClairePA]

The webservices can handle HELM strings where the repeating unit is a single monomer. e.g.

PEPTIDE1{A'2'}$$$$V2.0

It can also calculate the mol properties for a single repeated monomer in a longer polymer:

PEPTIDE1{A.G.A.C'5'.A}$$$$V2.0

However it can't calculate the molecule properties when the repeating unit is more than one monomer:

PEPTIDE1{A.(G.A.C)'3'.A}$$$$V2.0
