Summary: Use of OBPairTemplate causes linking error
Initial Comment:
I don't seem to be able to use OBPairTemplate or its typedef (OBPairInteger),
from within OB. It causes a linking problem:
For example, adding the following to MDLFormat.cpp gives:
// Store the Chiral Flag
unsigned int chiralFlagVal = ReadUIntField((line.substr(12, 3)).c_str());
OBPairInteger *chiralFlag = new OBPairInteger();
chiralFlag->SetAttribute("MOL Chiral Flag");
chiralFlag->SetValue(chiralFlagVal); // 1 ("Absolute Chirality"), 0
("Relative Chirality")
mol.SetData(chiralFlag);

However, using OBPairData instead is fine:
// Store the Chiral Flag
unsigned int chiralFlagVal = ReadUIntField((line.substr(12, 3)).c_str());
OBPairData *chiralFlag = new OBPairData();
chiralFlag->SetAttribute("MOL Chiral Flag");
chiralFlag->SetValue("1"); // 1 ("Absolute Chirality"), 0 ("Relative
Chirality")
mol.SetData(chiralFlag);
