New custom expressions

[Daniel Besse]

• PD models from meanmax (extract FTP/W'/etc or power at certain duration)
• meanmax function (from equallyspaced_stream)
• daily sum/avg/etc of activity metrics (such as TSS/TRIMP/etc)

[Daniel Besse]

• power and heartrate zones

[Daniel Besse]

• filter index / find : similar to Matlab with arrays indexed by boolean values and comparison operators on arrays
• sort / unique on array values

[Daniel Besse]

New expreval functions (see #61)

• PHP array functions sort/rsort/unique/reverse
• Comparison operators >/>=/</<=/==/!=

→ <<cset a8087ea39dc1>>

[Daniel Besse]

New expreval functions (see #61)

• Daily_sum for activities in date range (useful for PMC based on some other metric such as TRIMP)
• Select, to filter an array based on comparison operators

→ <<cset a41cd989b573>>

[Daniel Besse]

New expreval functions (see #61)

• meanmax
• selecting no type allows usage of default functions instead of error

→ <<cset 555481d3d3de>>

[Daniel Besse]

• NP_dist and HR_dist in week_summary

[Daniel Besse]

PD model and associative arrays in custom expressions (see #61)

• PD model, extracting parameters such as FTP.
• Associative arrays support.

Should add - Associative arrays specific indexing function. - PD model values from parameters.

→ <<cset b3c5a9b9ba53>>

[Daniel Besse]

Improvements to custom expressions (see #61)

• Variables save with = sign and simple recall by name
• Fixed about and other small bugs

→ <<cset d7cd0fb61250>>

[Daniel Besse]

Add classification of stream into bins (eg power distribution every x watts, hr every x bpm, etc). Define as generic function bin(array stream, number binsize) or distribution(...)

[Daniel Besse]

Distribution function (see #61)

→ <<cset dfb1f522e08e>>

[Daniel Besse]

Custom expressions (see #61)

• PD_model_values from parameters
• Support of 1e3 exponent format

→ <<cset 58f1c94c5730>>

[Daniel Besse]

Custom expressions and charts

• New functions: rand, range, array_combine, ... (see #61)
• plot_scatter and plot_line (close #51)
• example using plot_scatter for Quadrant Analysis (see #55)

→ <<cset 0d4614db5b10>>
