# Holds the state of the +describe+ block that is being
# evaluated. Every example (i.e. +it+ block) is evaluated
# in a context, which may include state set up in <tt>before
# :each</tt> or <tt>before :all</tt> blocks.
#
#--
# A note on naming: this is named _ContextState_ rather
# than _DescribeState_ because +describe+ is the keyword
# in the DSL for refering to the context in which an example
# is evaluated, just as +it+ refers to the example itself.
