Intersected with
e.g. QC10 = QC1 & QC5

Joined with
e.g. QC25 = QC7 | QC18

Joined without intersection
e.g. QC12 = QC5 ^ QC25

Joined with complement of
e.g. QC25 = QC1 \ QC2

Complement of contour area
e.g. Q12 = #Q11

Opening parenthesis
e.g. QC12 = QC1 * (QC2 + QC3)

Closing parenthesis
e.g. QC12 = QC1 * (QC2 + QC3)

Defining a single contour
e.g. QC12 = QC1
