Test and object struct members should be pointers

[ameihm0912]

As an example:

scribe/test.go

Line 31 in 69bc11b

EVR EVRTest `json:"evr,omitempty" yaml:"evr,omitempty"` // EVR version comparison

This could be defined as EVR *EVRTest

The benefit here is if set nil, omitempty would behave correctly and not include this in resulting JSON documents. Currently, the types when marshaled can include a lot of useless sections, and being able to omit these correctly if not required would make them much smaller.
