/**
 * This pipe can be used to shorten long text by a defined length.
 *
 * In markup:
 *
 * {{ str | dspTruncate:24 }}
 *
 * or
 *
 * {{ str | dspTruncate:24:'...' }}
 *
 * The first optional parameter defines the length where to truncate the string.
 * The second optional parameter defines the characters to append to the shortened string. Default is '...'.
 *
 * The advantage of this pipe over the default Angular slice pipe is the simplicity of adding
 *  additional characters at the end of the shortened string.
 * The same construct with Angular slice pipe looks as follow: `{{ (str.length>24)? (str | slice:0:24)+'...':(str) }}`.
