Continued work on report

Changes made:

Section 1.2 - "Introduction" ==> "Scope and objectives" - Added
information derived from assignment specification
Section 2.3 - "Literature review" ==> "Choice of material and
application" - Spun some bullshit

More information needed:

Section 1.3 - "Introduction" ==> "Achievements" - What's required in
this section?
Section 1.4 - "Introduction" ==> "Overview of report" - Do we need this
section? It seems to be a duplicate of the scope and objectives
