DefaultSelector

filter fragments by markers

This method is a bit involved but we have to consider lots of different cases

• if the marker is a tag or a section
• if the marker applies to the previous or next fragment
• if there is an irrelevant empty text between the marker and the fragment it applies to

filter fragments by name

filter fragments by previous execution and required status

select fragments by name, markers and previous execution

All the "appliesToNext = false" markers must be transformed into "appliesToNext = true" except when they are the end of a section.

This is because we want to visually include all of e2, e3, e4 in the following acceptance spec

e1 e2 ${section("x")} e3 e4 ${section("x")} e5
