Description

Currently ScriptFactory's dmlFromResource (and pydmlFromResource) resourcePath requires an initial slash, such as:

ScriptFactory.dmlFromResource("/scripts/datagen/genRandData4ALS.dml");

Update dmlFromResource to not require an initial slash so that it mirrors dmlFromFile's behavior:

ScriptFactory.dmlFromFile("scripts/datagen/genRandData4ALS.dml");
ScriptFactory.dmlFromResource("scripts/datagen/genRandData4ALS.dml");

// initial slash also still works for dmlFromResource
ScriptFactory.dmlFromResource("/scripts/datagen/genRandData4ALS.dml");
