Bases:
BaseSchemaDelphes schema builder
The Delphes schema is built from all branches found in the supplied file, based on the naming pattern of the branches. The following additional arrays are constructed:
Any branches named
{name}_sizeare assumed to be counts branches and converted to offsetso{name}
