## Repetitions
EFCurves add support for repetitions. Repetitions are expanded by replacing
occurrences of `|<text-to-repeat>|[<number-of-repetitions>]` with `number-of-repetitions` copies
occurrences of `(<text-to-repeat>)[<number-of-repetitions>]` with `number-of-repetitions` copies
of `text-to-repeat`.
For example:
* `M0 |h1 m1|[3]` expands to `M0 h1 m1 h1 m1 h1 m1`
* `M0 |h1 m1|[0]` expands to `M0`
* `M0 (h1 m1)[3]` expands to `M0 h1 m1 h1 m1 h1 m1`
* `M0 (h1 m1)[0]` expands to `M0`
### Nested repetitions
Repetitions can be nested.
For example `|M0 |h1 m1|[3]|[2]` expands to `M0 h1 m1 h1 m1 h1 m1 M0 h1 m1 h1 m1 h1 m1`.
For example `(M0 (h1 m1)[3])[2]` expands to `M0 h1 m1 h1 m1 h1 m1 M0 h1 m1 h1 m1 h1 m1`.
### Interaction between repetitions and expressions
`M0 |H{it + 1} m1][3]` expands to `M0 H1 m1 H2 m1 H3 m1`
`M0 (H{it + 1} m1)[3]` expands to `M0 H1 m1 H2 m1 H3 m1`
`M0 |H{index + 1} m{it}]{1.2, 1.3, 1.4}` expands to `M0 H1 m1.2 H2 m1.3 H3 m1.4`
`M0 (H{index + 1} m{it}){1.2, 1.3, 1.4}` expands to `M0 H1 m1.2 H2 m1.3 H3 m1.4`
