Probably, but not essential, I think. It would be nice, though if the 
user already knows what type of sequence she is creating. In other case 
we should use sequenceTypeForString to determine the symbolset. As you 
can see in BCSymbolSet, there are many interesting variations possible, 
eg dnaSymbolSet vs. dnaStrictSymbolSet. The latter only allows ACGT, 
the former all possible nucleotides. So it maybe can also be used 
instead of the skippingUnknownSymbols variable.
