Idea / Feature

We have a bunch of Properties and Methods in PropertyInfoExtensions.cs, PropertyInfoSelector.cs, MethodInfoSelector.cs, TypeSelector.cs in pending PRs. We can easily use them to extend to following Assertions:

PropertyInfoAssertions.cs and PropertyInfoSelectorAssertions.cs with:

• [Not]BeAbstract()
• [Not]BeStatic()

TypeSelectorAssertions:cs with:

• [Not]BeAbstract()
• [Not]BeSealed()
• [Not]BeStructs()
• [Not]BeInterfaces()

MethodInfoSelector.cs with:

• [Not]BeAbstract()

Some other ideas would be:
PropertyInfoSelector.cs and MethodInfoSelector.cs with:

• ThatAre[Not]Overridable

What do you guys think?
