Source task(s):

• AxoLabs format support Indigo#3152

• Check that symbols without brackets that represent nucleotides can be followed by symbol s

• Check that all symbols can exist at every position except symbols s (that can only be internal) and symbol p (that can only be terminal)

• Check that the logic behind the producing the AxoLabs string is the exact same as IDT, with the difference that symbols do not have any position indicators

• Check that all of the attachment point logic the same for AxoLabs as it is for IDT (replace IDT with AxoLabs)

• Check that all error messages on export the same for AxoLabs as they are for IDT ( Similar to IDT, not all nucleotides will exist in the library, for example: dR(A)P)

• Check that in case of import, where a symbol with brackets that is not defined in the Ketcher library exist, the monomer loaded as an unresolved AxoLab monomer

• Check that in case of import, where the string of symbols without brackets cannot be interpreted as a valid string using symbols above, the user get an error message: "The following string cannot be interpreted as an AxoLabs string."
