Really inefficient printing for large TimeArrays

[ValentinKaisermayer]

The main source seems to be this line:

TimeSeries.jl/src/timearray.jl

Line 297 in 0356f4b

strs = _showval.(values(ta))

only a very small subset of strs is used later.

Also if a TimeArray is a field of a struct the whole TimeArray is printed. Is there no summary view?

Regarding large TimeArrays, I put the following code in my startup.jl:

using TimeSeries
Base.show(io::IO, ::MIME"text/plain", ta::TimeArray) = if length(ta) > 6
    println("Showing only the head of ", length(ta), " rows…")
    show(io, head(ta))
else
    show(io, ta)
end

It's just my personal preference as I usually have many rows but relatively few columns.
